HARROW.

Specficacion of Letters Patent.

Paten.ted Jan. 6, 1920.

Application filed February 7, 1919. Serial No. 275,529.

Ta aZZ w7wm zt may concern:

Be it known that I, ORLANDO D. LENT, a c1tizen of the United States, residing at Peckskill, in the county of Westchester and State of New York, have invented new and useful hnprovements in Harrows, of which the following is a speoification.

The invention relates to harrows, and has for its object an implement adapted for uneven ground and for operation among obstacles, and that can be transported from place to place without loading on a wagon. The objects are attained by the means set forth in this specification and the accompanying dravvings, in both of Which like letters and numbers refer to similar parts in the several views. v

Referring to the drawings, Figure 1 is a plan of the harrow, Fig. 2 is a rear elevation of the harrow. Fig. 3 is an enlarged detail of a foldable part'of the harrow.

' Fig, 4 is an enlarged detail of the wheel featurcs of the harrow. Fig. 5 is a sicle elevation of the harrow folded for transportation.

Fig. 1 illustrates the various parts of the harrow, which comprises a frame made up of the cross-pieces a a and braoes 72 b, the braces set angularly in V fonn to give stiffness to the frame, and 130 aiford space for a floor c and foot brace Z; also for guides z' 2' for a wheel axle 7, the axle supporting a scat (Z. Between the ends of the cross-pieces a (1. are vibrating beams 6 6 that are held in place by pivotal bo1ts 1 1 1 1. At the forward ends of the beams are secured pivotal -brackets and swin in beams are pivoted in the brackets as at 8. These swinging bean1s are held within limite by means of the clamping bars L 7L that clamp one upon the other as at 2 3 and freely slide one upon the other, permitting the beams to swing toward and from the beams a 6 to which they are hinged. Stout springs 5 5, secured to the beams e 6 and thrusting against the swinging beams keep them n01- mally extended as in the figure. Harrow teeth are represented as at The posts z i that are;ereoted upon the braces b b, shown in all the figures except Fig. 3 and in enlarged detail in Fig. 4, are guides for an axis 7 that carries the wheels j. The axle is reduced in size at its ends to set easily in the guides, and have shoulders 9 adjacent to the guides -to prevent undue longitudinal motion of the-axle. A support 76 on the axle gives a support for a drivers scat (Z. VVhen the harrow is in use, the play of the axle vvithin its guides is such that the Wheels will always rest on the ground, but the weight of the wheels and the driver will not rst upon the harrow.

, Upon the swinging beams g g handles 0 are attached within reaoh from the seat of the driver. The hand1es are for the manipulation of the swinging side sections of the harrow, as when they are to be helped over an obstruction. Upon the outer ends of the swinging beams g 9* are buffer wheels 25 ournaled at 10, seen in all the figures except Fig, 4. These wheels have a double purpose. In harrowing, the swinging beams may make contact with a tree, to whch the beam would do no harm except as the end of the beam swept past it, when it would be likely to injure the bark of the tree. The wheel cases the passage of the beam past the tree and saves the tree from injury. The other purpose of the wheels will be referred 130 late1.

As thus far desoribed the ixnplement is usable in the fie1d for its purposes of a ha1row. As shown in Fig. 5 it is in shape for transporting. The swinging beams are brought to vertical positions as in Fig. 3. To retain them in such positions the beams c 6 are provided with bars 29, shown in all the figures except Fig. 4, and on enlarged scale in Fig. 3. When folded the bars over- 1ap the braces b 6 as in Fig. 3, resting upon the block elevations 7. Stout springs 8 with handles attached, are secured to the bar on and latch projections l0, Figs. 1 and 5, overlap the bars. VVhen the side sections are thus secured the harrow is turned upside clown as in Fig. 5. The rear of the harrow will ride upon the wheels The forward and will ride upon a 10019 "v, Figs. 1, 2 and 5, secured to the foot brace and the forward end of the harrow. A natural suggestion would be: a wheel in the 100p where it makes contact with the ground; but this harrow is designed for hilly lands, and the 100p is designed to constitute a brake on bill sides and it rides easfly upon other surfaces. By

means of a special devis shown plainly in Fig. 5, the devis can be hooked on the tail looard of a wagon, thus lifting the f0rward end of the harrow from the ground. Even for hauling distances, any necessity for placing the harr0w upon a wagon is obviated. The clevis is adjustable up or clown on the post m, by means of a pin m and several holes provided in the post, The devis hook 71 is provided with a pin n for use to prevent a whiffletree ring from d1opping out. The pin is to be backed ont when the devis is to be used as a hook for engagement with a wagon tai1-board.

The swinging beams make it possible to use this harrow where the ordinary harrow cannot be used. If there are, sa two or more trees near together the ground between them cannot ordinarily be reached. But with this harrow a tree may ha encountered and it W111 force the beani g toward the beam 6, but as soon as the tree is passed the spring 5 W111 force the beam out between the trees, so that all the ground can be treated. In stony ground the driver avoids obstructions by e1evating either side and the harrow adapts itse1f to uneven ground, as in Fig. 2, where the right hand side is seen t0 adapt itse1f t0 a s1ope of land.

Having described my invention what I daim and desire to secure by Letters Patent,

1. The combination in a harrow of a frame comprising front and rear bars united by V formed braces, vibrative beams pivoted between the ends of said cross bars, swinging beams hinged to said vibrative beams, the rear ends of said beams united by sliding clamping bars,a spring between the vibrative and swinging beams, bufi'er whee1s on the outer ends of the swinging beams, 11andles on the swinging beams, whee1 axle guides on the V bra-ces, an ax1e 10ose1y supported within said guides, wheels on the ax1e and a drivers seat on the ax1e.

2. The combination in a harrow of a frame comprising front and rear bars, V formed braces uniting said bars, vibrative beams pivoted between the ends of the cross bars, swinging beams hinged to said vibrative beams, s1iding clamping bars uniting the swinging beams with the vibrative beams, springs to act against the swinging beams, handles on the swinging beams, whee1 ax1e guides on the V braces, an aX1e 1oosely supported within said guides, whee1s and a drivers seat on the axle, means for c1amping the swinging beams at right angles to the main frame, a 100p fast to the upper side of the front of the harrow, and a hook on the forward end of the harrow adapted for a devis and for hooking to the tailboard of a wagon.

Signed at Peekski1l, county of 1Vestchester and State of New York, this 25th day of January, 1919.
